如何在Rails中实现条形码生成器

Question

How to generate barcode using a table id in ruby on rails. I am using Rails 5.1.4 and ruby 2.4.3. I have tried it with 'barby' gem but not sure how to mention require 'barby' and other dependencies in rails. When I am trying to enter require method in controller it is showing ' can not load barby' error.

Answer 1

Hi once you added gem in Gemfile and no need to require in controller in Ruby on Rails framework. Please follow the link below:

Generation bar-codes using barby

Answer 2

Rails在控制器中不允许使用“ require”选项，因此我在“ application.rb”中添加了所有需要的依赖项，并且对我有用。
